I have never worked with boost or the regex libary but need it as a dependency for another project. I could compile the libary for Visual Studio 2005 (VS8), but the docs give not a single hint how to compile with mingw on Windows (here XP). I tried gcc an generic, but that does not work H:\boost_1_40_0\libs\regex\build>mingw32-make -fgcc.mak gcc.mak:37: "Building Boost.Regex without ICU / Unicode support:" gcc.mak:38: "Hint: set ICU_PATH on the nmake command line to point " gcc.mak:39: "to your ICU installation if you have one." mkdir -p gcc mkdir -p gcc/boost_regex-gcc-1_40 Syntaxfehler. mingw32-make: *** [gcc/boost_regex-gcc-1_40] Error 1 H:\boost_1_40_0\libs\regex\build>mingw32-make -fgeneric.mak mkdir -p generic Ein Unterverzeichnis oder eine Datei mit dem Namen "-p" existiert bereits. Folgender Fehler trat auf: -p. mingw32-make: *** [generic] Error 1 How should it be done? Matthias
